Almost definitely. I ran this in using my setup which is 64-bit Linux
LilyPond running under WSL on 64-bit Windows 10. Peak memory usage
during compilation was around 4.4GiB, so there is no way a 32-bit
process could do this.

It took my computer about two minutes to process all 3000 measures,
which by the way typeset to 25 pages in the end--many of which are
virtually identical save for page and measure numbers.
